edges thereot rounded or curved, and as oneforni of a means for securing the casingor rim to the felly 3, screw bolts 5 may be employed,

which extendthrough the felly andeiigage in the casing or rim et, but any suitable fas- 1 teningineaiis for such purposeiii'iay be ein? ployed.- That portion of the riiii or casing forming the eripliery of the wheel is thickeiied or rein orced,asat 6to add strength 7 and rigidity t the rim or casing. .llie reinforced portion 6l has the inner side thereof provided with a circumfertitially;arf ranged groove'or seat 7 and )Vith para`l`lel. [rows of. circuinferentially disposed' oblong openings S, the openings of one row bein staggered withzlrelation to the openings o the other row. This construction best shown in Fig. 4 of the drawings, where it `will-bev observed that the reinforced ortion ofthe riiii'or casing presentsgaq's eleton frame work adapted to supportinserts or tread pieces, which will be presently" I11escribed indetti-il. The outer side of the rim or casing 4 is' provided with van annular opening-t) to permit o't'easy access being had y lo the interior olthe. riiii or casing. The

circumferential edges of the opening 9 are chaint'ered orgroo'ved tovprovide` a Seat l0 t'or ,an annular plate ll detacliably held in the seat l0. by'screws 12 or similar fastening means. r v

13 denotes ay circumferentially arranged yieldable sheath or -outer tube, which is placed iii the rini or casing l through the opening t) and is rectangular iii cross section to conform to the cross sectional area of -the rim or casing et. A'lhis-yieldable shield is made ot leather or other flexible material. Sole leather is preiferably used and' arranged with its grained surface 1nward. for a purpose that will hereinafter appear. The sheath can be iiiade of a single piece of leather and the longitudinal edges lii the drawings l denotes the huh'ot' a wheel provided with 'radially disposed Spokes 2 having the outer ends thcreotA coni ,n ected by a felly 3, these parts being coin- "inoiil to theordinary aiid weil known type i I sheath 13.A 'lliis air tube is also rectangular iii cross section, and in order that said tube cuniiereiitially of the telly b thc rini ottlieiiheel. The casing- 4 is -i'ecand forming i thereof laced or otherwise connected, or the edges can-be arranged to abut without fastening iiieaiis.

The grained surface of the leather. sheath 13 'is susceptibleto high polish, so that it constitutes practically an Vanti-frictional surface,.obviatin`g the liability of chaiin the air tube 14, which,

is preferably made o rubber.

17 denotes'tread blocks or pieces adapted tobe mounted in the reinforced portion 6 of the rim or casing 4 and rotrude through the openings 8. The tread blocks or pieces 17 are made of rubber sufficient-ly hardened to withstand considerable wear and tear, yet having sulicient elasticity to assist in cushioning the rim or casing 4. The tread blocks orv pieces -17 fill the openings 8 and have the inner s ides'thereof providediwith' heads 18 'adapted to engag in the seat and prevent the tread blocks or pieces from becomingaccidentally displaced. The ends of the heads 18 are rooved or rounded, as

at 19 to prevent the eads from injuring -or tube 14 and plate 11 remove Having now described my invention, what I claim as new,'1s:-
